Cadillac DTS Transmission Problems & Cost | 4T80E

The Cadillac DTS officially replaced the Cadillac DeVille in 2006 as the brand’s flagship model. This was mostly just a name change, as this big Caddy still offered full-size luxury, with Northstar V8 power. Under that powerful engine was the beefed up 4T80E transmission, which was designed to handle all of the torque that aluminum V8 put out. Although Cadillac DTS transmission problems are rare, they do still happen. So let’s find out when you can do about them.

Cadillac DTS Technical Service Bulletins (TSB)

TSB 08-07-30-009 – 4T80E transmission leak and slipping

Problem – One of the most common 4T80E transmission problems includes an ATF leak and slipping. Many times these two problems are related.
Solution – This problem is often caused by worn third clutch housing bushings, which can allow excessive transmission fluid build up at the axle seal. This condition can cause both the leak and the slipping. To correct it, a new third clutch housing with revised bushings will have to be installed.

TSB 08-07-30-016 – Slipping, refusal to shift, overheating

Problem – Slipping between the gears, overheating, refusal to shift out of a gear, and/or DTC P0894 or P0218, may be because by friction material debonding from the torque convertor clutch (TCC).
Solution – If the friction material has circulated throughout the transmission, the entire transmission may need to be replaced. It is possible to remove the material from the internal components (like transmission cooler lines and the valve body), but it depends on the extent of the damage.

Can I drive with a transmission problem?

Although many Cadillac DTS transmission problems won’t keep you from being able to drive the car, it’s still not a good idea. The 4T80E transmission is a heavy duty gearbox, and if something inside of it is broken, you can bet that it’s a major problem. And continuing to drive the car could make things a lot worse/more expensive to fix.

How often does a Cadillac DTS transmission need to be replaced?

If properly maintained, a Cadillac DTS 4T80E transmission can easily last for 130,000-180,000 miles. However, a good quality remanufactured 4T80E can last even longer.

How are Cadillac DTS transmission issues diagnosed?

The first step to figuring out what’s wrong with your Cadillac DTS 4T80E transmission, is to hook up a scan tool and pull the diagnostic trouble codes. Then the technician can perform a visual inspection to determine how to fix the problems.

How is a Cadillac DTS transmission replaced?

Replacing a Cadillac DTS 4T80 is fairly complicated, and typically requires the engine, transmission and front subframe to be removed. After separating the engine and transmission, the replacement 4T80E can be attached to the motor, and the whole assembly reinstalled in the car. There may be other methods of doing this, but that is the most accepted practice. However, the ECU/PCM will have to be reprogrammed / reflashed to accept the new transmission.

How to Solve Cadillac DTS Transmission Problems

Solution A: Buy a Used Cadillac DTS Transmission

Buying a used Cadillac DTS 4T80E from the local salvage yard might seem like the most economical solution at first. But with no way to verify the condition of the internal components, you may literally be buying someone else’s transmission problems. And that junkyard warranty may not cover labor charges if something goes wrong with the first used 4T80E.

Solution B: Buy a Rebuilt Cadillac DTS Transmission

Next up the ladder of logic, would be a rebuilt 4T80E transmission. In this scenario, a mechanic would take your existing gearbox and install a bunch of factory spec Cadillac transmission parts. When you compare this with a used Cadillac transmission, it does seem like the better choice. However returning the transmission back to stock will cause all of the original factory design flaws to return in the future. And that rebuilt transmission warranty is usually only good at the shop that built the transmission. So if you have transmission problem what your out of town, that warranty will do you absolutely no good.

Solution C: Buy a Remanufactured Cadillac DTS Transmission

The most viable solution to all of your Cadillac DTS transmission problems, is to get a remanufactured 4T80E transmission from a reputable supplier. They use are often upgraded beyond OE specs to extend their service life. And many will come with a nationwide warranty, that will provide you with coverage no matter where you travel.

2004 Cadillac Deville North Star what color is the wire from the break switch to the transmission for lock up

My 2006 DTS (55,648 original miles) has started dis-engaging (doesnt seem to be slipping, just dis-engaging) when making turns at low speed (5-10mph) it has happened 2-3 times in the last 3 days. When it does , I instantly stop pressing the gas and drop it into 2nd gear and it picks right up with no problem. It has had a leak for a while and I keep it no more than half to 1 qt low and I only drive locally within a 5-10 mile area as I work from home and only need to drive for groceries and errands. I checked it with my AL319 Autolink scantool and it has a transmission tab but has no current codes and none in history . Im trying to see if anyone found a fix for this issue and know what options may be available. please email me responses to
